Objective: To evaluate muscle strength, balance control and gait capacity in patients with multiple sclerosis (MS) and to study the correlations between these parameters.
Patients and methods: Twenty MS patients were evaluated in terms of knee muscle strength, gait and balance parameters. These evaluations were performed using an isokinetic dynamometer (the Cybex II(®)), a Bessou gait analyzer and a Satel(®) force platform, respectively. The patients' results were compared with those of a healthy control group.
Results: Hamstring and quadriceps peak torque values were lower in the MS group than in the control group. The sway area was greater in the MS group under eyes-open and eyes-closed conditions. The MS patients displayed lower gait speed, cadence and stride length. Hamstring and quadriceps strength values were significantly correlated with posture and gait parameters.
Conclusion: The present study revealed the value of an overall evaluation of knee muscle strength, gait and posture in MS patients.
